Ejemplos

En el ejemplo siguiente se generan los códigos hash de varios TimeSpan objetos mediante el GetHashCode método .

// Example for the TimeSpan::GetHashCode( ) method.
using namespace System;
void DisplayHashCode( TimeSpan interval )
{
   
   // Create a hash code and a string representation of 
   // the TimeSpan parameter.
   String^ timeInterval = interval.ToString();
   int hashCode = interval.GetHashCode();
   
   // Pad the end of the TimeSpan string with spaces if it 
   // does not contain milliseconds.
   int pIndex = timeInterval->IndexOf( ':' );
   pIndex = timeInterval->IndexOf( '.', pIndex );
   if ( pIndex < 0 )
      timeInterval = String::Concat( timeInterval, "        " );

   Console::WriteLine( "{0,22}   0x{1:X8}, {1}", timeInterval, hashCode );
}

int main()
{
   Console::WriteLine( "This example of TimeSpan::GetHashCode( ) generates "
   "the following \noutput, which displays "
   "the hash codes of representative TimeSpan \n"
   "objects in hexadecimal and decimal formats.\n" );
   Console::WriteLine( "{0,22}   {1,10}", "TimeSpan        ", "Hash Code" );
   Console::WriteLine( "{0,22}   {1,10}", "--------        ", "---------" );
   DisplayHashCode( TimeSpan(0) );
   DisplayHashCode( TimeSpan(1) );
   DisplayHashCode( TimeSpan(0,0,0,0,1) );
   DisplayHashCode( TimeSpan(0,0,1) );
   DisplayHashCode( TimeSpan(0,1,0) );
   DisplayHashCode( TimeSpan(1,0,0) );
   DisplayHashCode( TimeSpan(36000000001) );
   DisplayHashCode( TimeSpan(0,1,0,0,1) );
   DisplayHashCode( TimeSpan(1,0,1) );
   DisplayHashCode( TimeSpan(1,0,0,0) );
   DisplayHashCode( TimeSpan(864000000001) );
   DisplayHashCode( TimeSpan(1,0,0,0,1) );
   DisplayHashCode( TimeSpan(1,0,0,1) );
   DisplayHashCode( TimeSpan(100,0,0,0) );
   DisplayHashCode( TimeSpan(100,0,0,0,1) );
   DisplayHashCode( TimeSpan(100,0,0,1) );

Dos TimeSpan objetos pueden tener el mismo código hash aunque representen valores de hora diferentes.

Se aplica a
